Detailed Description

template<int spacedim, class Value, typename Fn, class... InputFields>
class FieldModel< spacedim, Value, Fn, InputFields >

Class representing field computing form results of other fields.

Example of usage:

// Functor class with defined operator ()
class FnProduct {
public:
Vector operator() (Scalar a, Vector v) {
return a(0) * v;
}
};
...
// Create ElementCacheMap
std::shared_ptr<EvalPoints> eval_points = std::make_shared<EvalPoints>();
eval_poinzs->add_bulk<3>( quad ); // initialize EvalPoints
ElementCacheMap elm_cache_map;
elm_cache_map.init(eval_points);
// Definition of fields
... // fill data to fields f_scal, f_vec
// create instance FieldModel class, use helper method Model::create to simply passsing of parameters
auto f_product = Model<3, FieldValue<3>::VectorFixed>::create(FnProduct(), f_scal, f_vec);
// set field on all regions
result.set_mesh( *mesh );
result.set_field(mesh->region_db().get_region_set("ALL"), f_product);
result.cache_allocate(eval_points);
result.set_time(tg.step(), LimitSide::right);
// cache_update
result.cache_update(elm_cache_map);
